FLAMING-ARC ATTACHMENT FOR INCLOSED-ARC LAMPS.

Continuation in part of application Serial No. 742,643, filed January17, '1913.

Serial No. 777,458.

To all whom it may concern:

Be it known that I, HENRY Gr. Drnn, a citizen of the United States,residing at Collingswood, in the county of Camden and State of NewJersey, have invented a certain new and useful F laming-Arc Attachmentfor Inclosed-Arc Lamps, of which the following is a specification, thepresent case being a continuation in part of my application for LettersPatent filed January 17 1913, and Serial No. 742,643.

The principal objects of the present invention are first, to provide, asa new article of manufacture, an attachment complete in itself, which'isadapted for detachable connection to any of the well-known types of socalled inclosed arc lamps now in use, whereby any of such are lampswithout change of construction of its parts may be converted into aflaming arc lamp at comparatively small cost; second, to provide such anattachment consisting primarily of a translucent arc inclosing chamberand a separable condensing chamber, the bottom of which is oftranslucent material and the continuous top of which is of opaque material; third, to provide such an attachment designed to prevent rays oflight being diffused from the condensing chamber top but calculated topermit rays oflight being diffused from the condensing chamber bottomand from the arc inclosing chamber over a relatively large space.

Other and further objects of the invention relate to the providing ofgeneral details of construction and arrangement and combination of partsas will hereinafter more fully appear.

With these objects in view the invention consists of the improvementshereinafter de scribed and finally claimed.

The nature, charactertistic features and scope of the invent-ion will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part thereof, and in which:

top of which is of opaque material. top of the two part condensmgchamber in Patented June 23, 1914.

This application filed July cleaning and trimming purposes, and Fig. 4,1s a view in section taken upon the line 44 of Fig. 3.

Referring to the drawings, there is disclosed a physical embodiment ofthe invention, the same being constructed in accordance with the modebest known to me at this time for practising the invention. Obviously,various details of construction and arrangement of parts may besubstituted without departing from the spirit of the invention and Iwish it understood that I consider mere changing of details as comingwithin the scope of the present invention.

The present attachment is so designed that it may, at small cost, bereadily and expeditiously attached to any type of the so called inclosedarc lamps now in use with out reconstruction of the lamp parts, wherebythe same may be converted into a flaming arc lamp. Thus by the use ofsuch attachment an inclosed arc lamp, may if desired, be interchangeablyused as an arc lamp or a flaming arc lamp, thereby enhancing theefficiency and commercial value of the same.

The attachment of the invention is complete in its self and constitutesa new article of manufacture. It consists primarily of a translucent arcinclosing chamber A, and a two-part, separable condensing chamber B, thebottom of which condensing chamber is of translucent material, and theThe practice is preferably formed of metal and consists of a continuousdome-shaped structure 10, centrally apertured for a purpose to bepresently described. As clearly shown in Fig. 2, the dome 10, consideredin plan stituting the arc inclosing chamber A. As clearly shown in Fig.3, the rim of the glassware C is removably seated upon the flangedportion 14 of a metallic ring 15, which flanged portion is provided witha packing ring or gasket 16, of asbestos or the like. The ring 15, isarranged to fit snugly within the rim 12, of the dome piece 10, and theupper edges of the ring 15, and glassware C are held in abuttingposition with the underside of the ring 13, by means of suitableclamping mediums, shown in the drawing as being pivotal catches 17. Theparts thus clamped together form a relatively airtight structure.

\Vithin the condensing chamber B, and secured to the dome 10, as byscrews 18, is a generally cylindrical member 19 which is in practicemade in one piece and protrudes downward into the open top of thebulb-like structure D, as clearly shown in Fig. 1. The outside diameterof that part of the member 19, which extends into the bulb-likestructure is of a diameter slightly smaller than the inside diameter ofsaid structure at that point, so that a small annular space F, ispresent between said parts, see Fig. 1. From the bottom of the member19, to within a short distance of the top of said member the wallsthereof are solid. Immediately adjacent the dome top, however, the wallsof the member 19 are slotted as at 21, for a purpose to be presentlydescribed.

Fitted between the dome 10 and the top of the member 19, is the flangedportion of an inverted cone frustum shaped gas diverter 22, the body ofwhich extends through the open top of the member 19, well within thesame, and to a point below the slotted walls 21. This gas diverter 22,is of insulating material and as shown closes the open top of the member19. It is also formed at its top to penetrate the central opening in thedome 10, and is centrally apertured for the passage therethrough of anupper electrode.

Depending from lugs 23, carried by the member 19, are rods 24, whichsupport a carbon holder 25. As shown the carbon holder 25, extends towithin a short distance of the closed bottom of the are inclosingchamber A.

Fixed exteriorly upon the dome 10, is a generally dish-shaped supportingattachment 26, having an annular flanged portion 27. Fitted over thedish-shaped part 26, is a top plate 28, centrally apertured toaccommodate an upper electrode. This plate 28, is removably attached asclearly shown in Fig. 2. As shown the plate 28, marginally considered,is provided with a series of slots 29, communicating with relativelylarge apertures 39. Screws 31, pass through the slotted portions of theplate 28, and engage the flange 27 of the dish-shaped mem ber 26. Bythis construction, the plate 28, may be readily removed by unlooseningthe screws 31, and partially rotating the plate 28, to the right in Fig.2, until the apertures 30, registered with the head of the screws 31,whereupon the plate 28, may be readily removed.

To apply the above described attachment to an inclosed are lamp it ismerely necessary'to remove from the body of the arc lamp its globe andlower carbon holder. The top plate 28, of the present attachment istheir suitably drilled to accommodate screws for securing the same tothe body of the are lamp and when the top plate has been made fast theattachment is secured to said top plate by passing the heads of thescrews 31, through the apertures, 30, and slightly rotating theattachment to the left in Fig. 2, at which time the screws 31, aresecured to place. In operation, the vapors, gases and smoke given cit bythe electrodes are caused by the heat of the are to pass upwardlythrough the generally contracted bulblike structure D, and quicklyascend through the opening 20, in the member 19, and pass out into thecondensing chamber through the slots 21, the part 22, serving to divertor spread the vapor, gases and smoke toward said slots in this upwardmovement. Thus the quick ascension of the vapors, gases and smoke servesto reduce gaseous condensation deposits upon the bulb-like structureforming the are inclosing chamher. The vapors, gases and smoke leave themember 19, immediately adjacent the top of the condensing chamber andcirculate therearound in a continuous cycle, until condensation occurs.As the metallic dome 10, by reason of the specific construction shown isrelatively cooler than is the annular dishshaped bottom of thecondensing chamber, rapid condensation is effected and condensationproducts accumulate both upon the dome 10, and upon the dished portionof the condensation chamber bottom. Thus, during the circulation of thecombustion products within the chamber B, the gases returning to the arcinclosing chamber are substantially free from condensable products andthe generally curved part 32, of the member 19, cooperates with thesmall annular space F, to bafiie and prevent their return. It may bestated at this time, that the part 19, further serves to prevent to agreat degree rays of light finding their way to the condensationchamber, and those rays of light which do reach the condensing chamberare reflected by the dome piece 10, and diffused through the glassbottom C, even though condensation deposits are present thereon. It maybe further stated that with deposits of condensation upon the dishshaped condensation chamber bottom additional reflection of light isprovided for as rays of light impinge thereon from the lighttransmitting part of the attachment.

The dome 10, and ring 15, are connected together by short chain sections34, so that, when it is desired to clean the attachment parts, or trimthe lamp, the pivotal clips 17, are unfastened, so that the ring 15,together with the glassware may conveniently be dropped to the positionshown in Fig. 3.
